title: Activities of daily living, social functioning and their determinants in persons with psychotic disorder.
abstract: OBJECTIVE
  The determinants of everyday functioning in persons with psychotic disorder have not been widely studied in community dwelling samples. Our aim was to investigate limitations in everyday functioning among subjects with psychotic disorders in a population-based study.
  
  
  METHODS
  Everyday functioning was assessed in a nationally representative sample of 7112 persons aged 30+ using interviewer observations and self-reports, while verbal fluency and memory were also measured. Diagnostic assessment of DSM-IV psychotic disorders was based on SCID interview and case-note data. Lifetime-ever diagnoses of psychotic disorder were classified into schizophrenia (n=61), other non-affective psychotic disorders (ONAP) (n=79) and affective psychoses (n=45).
  
  
  RESULTS
  Non-affective psychotic disorder was significantly associated with limitations in everyday functioning, as well as with deficits in verbal fluency and memory. Negative symptoms, depression, age, gender, verbal memory deficits, and reduced visual acuity were predictors of limitations in everyday functioning even after controlling for sociodemographic factors and chronic medical conditions, and difficulties in social functioning were also related to expressive speech problems.
  
  
  CONCLUSIONS
  Persons with schizophrenia and ONAP have significantly more problems in everyday functioning than the general population. One significant predictor of problems was reduced visual acuity, which at least in some situations could be easily corrected.
